The Perception of Risk of Heart Disease Scale: development and psychometric analysis.
Perception of risk of getting heart disease is an important predictor of individuals' engagement in a healthy lifestyle. This study describes the development and testing of the Perception of Risk of Heart Disease Scale (PRHDS). The 20-item instrument was tested in successive steps with 295 individuals for internal consistency, test-retest reliability, and construct validity. The three subscales of dread risk, risk, and unknown risk had internal consistency values ranging from .68 to .80. The total scale alpha was .80. Evidence of the instrument's stability over time was supported by subscale test-retest reliabilities ranging from .61 to .76. Construct validity was documented with a positive correlation between PRHDS and the Health Promotion Lifestyle Profile II (r = .20 to .39). Further psychometric testing of the PRHDS in a larger sample with a heterogeneous cultural background is recommended.
